2. WHAT IS NETWORKING HARDWARE?
• Networking hardware includes all computers,
peripherals, interface cards and other
equipment needed to perform data-processing
and communications within the network.

5. FILE SERVER
It is a very fast computer with a large
amount of RAM and storage space,
along with a fast network interface card
It is where data files and application
software needed to be shared are being
stored.
7. VoIP Phone
A VoIP phone or IP phone uses
voice over IP technologies for
placing and transmitting
telephone calls over an IP
network, such as the Internet,
instead of the traditional public
switched telephone network
8. Closed-circuit television
(CCTV)/ Security Camera
A closed-circuit television
camera can produce images
or recordings for
surveillance or other private
purposes. Cameras can be
either video cameras, or
digital stills cameras
9. •Mobile Devices
is a computer small
enough to hold and operate in
the hand. Typically, any handheld
computer device will have an LCD
or OLED flatscreen interface,
providing a touchscreen interface
with digital buttons and
keyboard or physical buttons
along with a physical keyboard.
11. HUB
• A hardware device that contains multiple
independent but connected modules of
network and internetwork equipment
• Hubs can be active (where they repeat signals
sent through them) or passive (where they do
not repeat but merely split signals sent
through them).
12. SWITCH
Provides a central connection point
for cables from workstations, servers, and
peripherals.
They memorize addressing of
computers and send the information to
the correct location directly.
13. WIRELESS ACCESS POINTS
• In computer networking, a wireless access
point (WAP), or more generally just access
point (AP), is a networking hardware device
that allows other Wi-Fi devices to connect to
a wired network. As a standalone device, the
AP may have a wired connection to a router,
but, in a wireless router, it can also be an
integral component of the router itself. An
AP is differentiated from a hotspot which is
a physical location where Wi-Fi access is
available.
14. REPEATER
• amplifies the signal it receives and
rebroadcasts it
• Repeaters can be separate devices or they can
be incorporated into a concentrator
15. BRIDGE
• A bridge monitors the information
traffic on both sides of the network
so that it can pass packets of
information to the correct location
• A bridge is a device that allows
you to segment a large network
into two smaller, more efficient
networks
• If you are adding to an older
wiring scheme and want the new
network to be up-to-date, a
bridge can connect the two.
16. ROUTER
• A router translates information
from one network to another
• it is similar to a superintelligent
bridge.
• Routers select the best path to route a
message, based on the destination
address and origin..
The router can direct traffic to prevent
head-on collisions, and is smart enough to
know when to direct traffic along back roads
and shortcuts.
While bridges know the addresses of all computers on each side
of the network, routers know the addresses of computers,
bridges, and other routers on the network
17. NETWORK INTERFACE CARD
PROVIDES THE PHYSICAL CONNECTION
BETWEEN THE NETWORK AND THE COMPUTER
WORKSTATION.
Network interface cards are a major factor in determining the
speed and performance of a network
Most NICs are internal, and they are included in the
purchase of most computers
A network interface controller (NIC, also known as a
network interface card, network adapter, LAN
adapter or physical network interface,[
18. MODEM
Modem: device that modulates an
analog "carrier" signal (such as
sound) to encode digital
information, and that also
demodulates such a carrier signal
to decode the transmitted
information. Used (for example)
when a computer communicates
with another computer over a
telephone network
